ProDAQ 3080 Gigabit LAN Slot-0 Interface User Manual
Chapter 1 - Introduction
1.1
Overview
The ProDAQ 3080 Gigabit Ethernet VXIbus Slot-0 Interface provides access to VXIbus
instruments through a standard Gigabit LAN interface using the VXI-11 protocol. It is
designed to function as a bridge between the established, time-tested and proven base of
VXIbus instruments and the IEEE 802 Ethernet, which allows you to build any size of test
and measurement system simply by connecting the instruments via standard LAN to your
computer.
The ProDAQ 3080 provides up to two standardized Gigabit LAN interfaces with support for
the VXI-11 protocol and an embedded WEB interface. It utilizes the new Tundra Tsi148
bridge to support the 2eVME block transfers specified in the revision 3.0 of the VXI
standard in addition to all standard transfer modes. This allows for high-speed data
transfers while maintaining backward compatibility to existing VXI rev. 1.3, 1.4 and 2.0
instruments.
The ProDAQ 3080 is fully compliant to the VXIplug&play standard. Access to the 3080 and
the VXIbus instruments is provided through a standard VISA library. This allows for
backward compatibility with existing VXIplug&play drivers and application software. The
VXIbus resource manager is embedded in the 3080 firmware and automatically executed
at power-up. The embedded WEB interface allows configuring and controlling the ProDAQ
3080 VXIbus Gigabit LAN Slot-0 interface and provides access to the VXIbus instruments
via a standard WEB browser.
Communication with the host processor via the front-panel Gigabit Ethernet port(s) is done
via standard Cat 5e Ethernet cable for distances up to 200 meters. Low-cost Gigabit
Ethernet switches can be used to increase the maximum distance as well as to connect
multiple mainframes to a single host or to integrate multiple mainframes and hosts into a
network.
Note:
To achieve maximum performance, connect the ProDAQ 3080 to a host featuring
a Gigabit LAN interface. If you are using switches or hubs in your network
connection, make sure that they conform to the Gigabit Ethernet standard and
are able to operate at that speed.
For synchronization in legacy systems, the ProDAQ 3080 features a front-panel trigger
input/output and CLK10 I/O via SMB connectors.

Chapter 2 - Getting Started
The ProDAQ 3080 Gigabit Ethernet VXIbus Slot-0 Interface is a single slot, C-size VXIbus
instrument and can be installed in any slot of a standard C-size VXI mainframe. To be
Slot-0 controller for the VXIbus system, it must be installed in the leftmost slot of the VXI
mainframe (slot “0“). If it is installed in any other slot of a VXI mainframe, all slot-0
capabilities (MODID, CLK10, etc.) will be automatically turned off.
Attention:
To allow access to instruments in the VXI mainframe, the ProDAQ 3080 MUST be
installed in the leftmost slot of the VXI mainframe (slot "0"). Installing it into any
other slot will only allow you to access the device itself (e.g. for configuration
purposes).
Installing it into any other slot will only allow you to access the device itself (e.g. for
configuration purposes). If you do so, please make sure to set up the logical address
correctly to avoid any collision with a slot-0 device already present in the mainframe.
Note:
The ProDAQ 3080 Gigabit Ethernet VXIbus Slot-0 Interface does not extend the
VXI backplane between mainframes in a multi-mainframe system. This means
that devices sharing the local bus must be installed in the same mainframe.
To install the ProDAQ 3080 Gigabit Ethernet VXIbus Slot-0 Interface and the necessary
software on your system, use the installation sequence as described in this chapter:





2.1
Step 1: Unpacking and Inspection
Step 2: Installing the ProDAQ 3080
Step 3: Connecting the ProDAQ 3080 Interface
Step 4: Bustec VISA installation (please refer to Bustec VISA Library and
Tools User Manual)
Step 5: Accessing the ProDAQ 3080
Unpacking and Inspection
All ProDAQ modules are shipped in an antistatic package to prevent any damage from
electrostatic discharge (ESD). Proper ESD handling procedures must always be used
when packing, unpacking or installing any ProDAQ module, ProDAQ plug-in module or
ProDAQ function card:



Ground yourself via a grounding strap or similar, e.g. by holding to a grounded
object.
Remove the ProDAQ module from its carton, preserving the factory packaging
as much as possible.
Discharge the package by touching it to a grounded object, e.g. a metal part of
your VXIbus chassis, before removing the module from the package.



3080-XX_UM
Inspect the ProDAQ module for any defect or damage. Immediately notify the
carrier if any damage is apparent.
Only remove the module from its antistatic bag if you intend to install it into a VXI
mainframe or similar.
When reshipping the module, use the original packing material whenever possible. The
original shipping carton and the instrument’s plastic foam will provide the necessary
support for safe reshipment. If the original anti-static packing material is unavailable, wrap
the ProDAQ module in anti-static plastic sheeting and use plastic spray foam to surround
and protect the instrument.
2.2
Installing the ProDAQ 3080 Interface
To prevent damage to the ProDAQ module being installed, it is recommended to remove
the power from the mainframe or to switch it off before installing.
2.2.1 Configuring the Logical Address
To allow a host to control the VXI devices in the mainframe via the network using the
ProDAQ 3080, the ProDAQ 3080 must be installed as the slot-0 controller for the
mainframe, i.e. it must be installed in the leftmost slot of the mainframe (slot "0") and must
be configured for using logical address 0 (zero).
The logical address switch is located on the back of the module. Figure 1 shows the
location of the logical address switch on the ProDAQ 3080. Set each switch to ‘Off’ for a
logical one (1) and to ‘On’ for a logical zero (0). The picture shows the address switch set
to logical address zero (0).

2.2.2 Installing the ProDAQ 3080 into the Mainframe
Insert the module into the mainframe using the guiding rails inside the mainframe as
shown in Figure 2. Push the module slowly into the slot until the backplane connectors of
the module seat firmly in the corresponding backplane connectors. The top and bottom of
the front panel of the module should touch the mounting rails in the mainframe.
Figure 2 - Installing the ProDAQ 3080 into a C-Size Mainframe
Note:
To ensure proper grounding of the module, tighten the front panel mounting
screws after installing the module in the mainframe.
2.3
Connecting the ProDAQ 3080 Interface
The ProDAQ 3080 is equipped with one or two standard RJ-45 network connectors,
accepting standard Cat 3, Cat 5, Cat 5e and Cat 6 Ethernet cables. However, to run the
interface in a network using 1000BASE-T mode, in minimum Cat 5e (better Cat 6) cables
are required.
The figure on the next page shows the location of the LAN connector(s) on the ProDAQ
3080-AA and ProDAQ 3080-BA front panel. The connector features two LED indicators
showing the speed and the link status of the connection made (see Table 1).

ProDAQ 3080 Gigabit LAN Slot-0 Interface User Manual
Accessing the ProDAQ 3080
In order to get the full access capability to ProDAQ 3080 (mapping to VXI), the Bustec
VISA must be installed and used for communication. Other connection methods – to the
web interface, or using TCPIP-type VISA resource may be achieved by, respectively, any
web browser or VISA library.
By default, the ProDAQ 3080 uses DHCP to configure its network interface. If no DHCP
server is found in the network, it will attempt to obtain a network address using AutoIP.
The AutoIP addresses are allocated from the reserved range 169.254.1.0 169.254.254.255. The ProDAQ 3080 will select a random address from that range. If the
address is already in use, another trial is done until there are no conflicts. By using the
embedded web interface, the ProDAQ 3080 can be also configured to use a static IP
address.
If the IP address is known, the web interface can be opened by typing the address in any
web browser:
http://<IP ADDRESS>
The device can be also accessed (with any VISA) using the following resource string:
TCPIP<n>::<IP ADDRESS>::vxi0::INSTR
2.4.1 Accessing the ProDAQ 3080 using Multicast DNS
ProDAQ 3080 announces, using mDNS that it provides “http” and “vxi-11” interfaces. In
order to make use of it, a Multicast DNS service must be running on the host. With mDNS
host name it is possible to access the device not knowing the actual IP address.
Multicast DNS services are provided for Windows by Bonjour
www.apple.com) and for Linux by Avahi (available at www.avahi.org).
(available
at
The default mDNS service name for ProDAQ 3080 is:
Bustec Ltd – ProDAQ 3080 – <SERIAL NUMBER>
And the default host name is:
prodaq3080-<SERIAL NUMBER>.local
With the default host name, accessing the web interface is achieved with the following
HTTP address:
http://prodaq3080-<SERIAL NUMBER>.local
And the VISA resource can be accessed with:
TCPIP<n>::prodaq3080-<SERIAL NUMBER>.local::vxi0::INSTR

ProDAQ 3080 Gigabit LAN Slot-0 Interface User Manual
3080-XX_UM
The host name may be changed by the user, so having an automatic search for mDNS
enabled devices is very useful. The user doesn’t need to know neither the IP address nor
the host name of the device. If Bonjour (Windows) or Avahi (Linux) is running on the host,
the Bustec Agent tool makes use of it. It scans for the available devices, lists them and
allows opening their web interfaces.
Figure 4 - Using Bustec Agent to search for mDNS enabled devices
There are other tools that give similar functionality as well. For example: DNSSD add-on
for Firefox, available at addons.mozilla.org.

2.4.2 Discovering the ProDAQ 3080 using VXI-11 Broadcast
The Bustec VISA Configuration Utility can be used to discover ProDAQ 3080 modules
using the VXI-11 protocol. To discover ProDAQ 3080, the device type VXI with device
number 0 must fit within the search criterion (it does by default). The discovered ProDAQ
3080s are added to the Network Instruments list as VISA resources:
TCPIP<n>::<IP ADDRESS>::vxi0::INSTR
For the detailed description of the procedure please refer to Bustec VISA Library and
Tools User Manual.

MAC address
Shows MAC address of the Network Interface.
Current IP configuration
Displays currently assigned: IP Address and Subnet Mask – for
each of two Network Interfaces, Default Gateway – only for the
primary interface and DNS servers – common.
TCP/IP mode
Specifies whether the device shall use a DHCP server in the
network, or AutoIP protocol to automatically obtain the IP
configuration, or maybe the static IP configuration defined in the
form below.
More than one option may be selected. The priority is as follows:
DHCP → AutoIP → Static. For example, if DHCP and Static are
selected and DHCP fails, the Static configuration is set.
Note: Only one of the Network Interfaces may use AutoIP option. If
none of them are configured to use DHCP, at least one DNS server
IP address must be defined by the user.
IP Address
If "Static IP" was selected as the TCP/IP mode, this field allows
assignment of a static IP address to the ProDAQ 3080 LAN
interface(s).
Subnet mask
If "Static IP" was selected as the TCP/IP mode, this field allows
assignment of a static subnet mask address to the ProDAQ 3080s
LAN interface(s).
Default Gateway
If "Static IP" was selected as the TCP/IP mode, this field allows
assignment of a static default gateway for the routing of IP packets.
Note: Due to common routing rules it is possible to define one
Default Gateway – here only for the primary Network Interface.
DNS Servers
If none of the Network Interfaces are configured to use DHCP,
these two fields allow you to specify the DNS server the ProDAQ
3080 will use for name resolving. Otherwise it is possible to select
whether the DNS servers’ IP addresses shall be acquired
automatically (DHCP) or user-defined (Static).
MTU
Maximum Transmission Unit (MTU) – maximum size (in bytes) of
an IP packet that can be transmitted without fragmentation
(including IP headers, but excluding headers from lower levels in
the protocol stack). Each Network Interface has own MTU setting.
The default value for a typical network is 1500 bytes. It can be
defined as high as 9000 bytes (jumbo frames). For correct
interoperation, the whole network must have the same MTU. To
achieve the maximum performance, it is recommended to
configure the network to work with a MTU settings as high as
possible.

3.6.4 Interrupt Configuration
The Interrupt Configuration page allows configuring the usage of the VXIbus interrupt
lines in the allocation mechanism of the VXI resource manager.
Figure 21 - Interrupt Configuration Page
For each of the VXIbus interrupt lines (Level 1 to Level 7) one of two settings for the
assignment can be chosen :
Auto
This setting will allow the resource manager to use the interrupt line
for this level in his allocation mechanism.
None
This setting will prevent the resource manage to use the interrupt line
for this level in his allocation mechanism. This setting must be used if
a instrument in the system does not allow the dynamic allocation of
interrupt lines and wants to use one or more lines permanently
allocated.

Chapter 4 - Remote Operation
The ProDAQ 3080 Gigabit LAN Slot-0 Interface features a VXI-11 RPC server, which
allows the access from remote hosts via the VISA library. This access can be done in two
ways, either by accessing the VXIbus instruments separately as TCP/IP instruments or by
mapping the ProDAQ 3080 into the remote VISA configuration as a standard VXIbus
interface.
4.1
TCP/IP Instrument Access
To access the VXIbus instruments installed in the same mainframe as the ProDAQ 3080
interface, you will need to use resource strings in the format
TCPIP[board]::<host address>::<interface>,<logical address>[::INSTR]
where [board] is the optional index of the LAN interface devices (as default, device 0 is
used); <host address> specifies the host name or IP number of the ProDAQ 3080
interface; <interface> specifies which interface on the ProDAQ 3080 to use (only "vxi0" is
supported) and <logical address> specifies the logical address of the VXIbus instruments
to access. The specification "::INSTR" is optional.
Example: If the ProDAQ 3080 is configured to use IP address 192.168.2.80 and is
installed in the same mainframe as a VXIbus device configured for using logical address 2,
access to this device can be gained by using the open statement
status = viOpen(rm_session,
“TCPIP::192.168.2.80::vxi0,2::INSTR”,
VI_NULL, VI_NULL, &instr_session);
Hence, as the VXI-11 standard allows only for read/write RPC messages, only message
based VXIbus instruments can be operated in this way.
4.2
Mapped Interface Access
To gain access to all VXIbus instruments via the ProDAQ 3080 Gigabit LAN Slot-0
Interface, it is necessary to map the ProDAQ 3080 as a standard VXIbus interface onto the
host system.
To do so, select the “Bustec VISA Configuration Utility” in the Bustec VISA program group
created during the installation of the VISA library (“Start”  “Programs”  “Bustec
VISA”). Alternatively you can use a link in Bustec Agent. This will start the configuration
tool for the VISA library and attached hardware interfaces.

Figure 25 - VISA Configuration Utility
To add a new interface, select “Add Interfaces”. A new dialog “Add New Interface” is
shown with a list of all devices found in the system. The already configured are disabled.
Each interface is listed with its type and with a description containing the serial number of
the device.
To map a remote interface, select the "Map Network Interface" button at the bottom.
Figure 26 - Add New Interface Dialog
In the "Map Network Interface" dialog you can specify the network address of the remote
interface and the local interface on the remote server to use. In case ProDAQ 3080 only
“vxi0” is supported.
The TCPIP interface number is a virtual value. It allows differentiation of TCPIP interfaces
in case of conflict management when there are multiple VISAs installed in the system.

Figure 27 - Map Network Interface Dialog
Click “Ok” to add the network interface. The procedure can be repeated to add more
ProDAQ 3080 network interfaces for mapping.
Once the network interfaces are added, they can be configured with VXI interface
numbers. The VXI interface numbers are assigned automatically from the pool of not yet
used values. In order to change them, just select an interface and modify the value using
the spin box control in the bottom.
Figure 28 - Updated Available Interfaces List
Finally click “Add all” or “Add selected”. The list in the main dialog will be updated with the
newly added interfaces.

As the remote interface is now mapped as a standard VXIbus interface onto the computer,
the resource manager need to run to retrieve the instrument configuration from the remote
host. To run the resource manager, select “Bustec VXIbus Resource Manager” from the
Bustec VISA program group in the start menu (“Start”  “Programs”  “Bustec VISA”) or
use the link in Bustec Agent.

Note
The VISA library is a shared library that initializes itself when it is first loaded by
an application. Applications started while the VISA library is already loaded just
share this configuration. Only when all applications using the VISA library are
stopped, it will be unloaded by the system. Therefore all applications using the
VISA library must be closed before running the resource manager or using the
VISA configuration utility. Take special care while using integrated development
environments, they will keep the VISA library loaded even when the application
developed in them was stopped.
When the Resource Manager retrieves the configuration from the ProDAQ 3080 host, it’s
possible to access the remote VXI resources using VXI rather than TCPIP interface.
The Bustec VISA Assistant tool can be used to easily access the configured interfaces
without programming.
Figure 31 – Bustec VISA Assistant
For more information on the tools coming with the Bustec VISA and application
programming using the VISA library please refer to Bustec VISA Library and Tools User
Manual.
